The Mountain Lakes Public Library Makerspace partners with St. Joseph's School for the Blind teacher Lauren Marron and her students to develop accessible resources. This is a four digit abacus that was designed in Tinkercad. You can customize the abacus base color, 3d printed rods, and bead color (beads are from Amazon). Additionally, you can personalize the abacus by adding and / or braille to this abacus, Here is the Tinkercad link with generic text and braille labels. Please copy into your own Tinkercad to modify. We use the Openscad Braille Generator to create .stl braille labels, which are then imported into Tinkercad. https://www.tinkercad.com/things/62va2aOsOu9-mighty-leelo/edit?sharecode=HW6orzyhym9DGmFzpIj7Ji2qiTZx2s9mNZdEo9omdPE Thank you Leona Holloway at Monash University for the Braille STL Label Generator. https://www.thingiverse.com/thing:4167866 After printing the rods, place rod gently through one end hole.
